I do not understand your intervention, I thank you again for the method of writing code but it did not work, I immediately send a comment with the error message but not received back. In the end, what is your goal? to lower me ? do not allow me to get help? but why, do I disrespect you once? I'm sorry but I do not understand you anymore.

Erreur de compilation pour la carte Arduino/Genuino Uno

Well because you clearly did NOT use the code I gave you. I have no Serial.begin(F(9600)); in the code I wrote for you for example, so I have no clue what you are doing and which code you have been trying. Not mine clearly.
